Abstract (en)
The present invention provides an alumina-based thermally conductive oxide that is excellent not only in thermal conductivity but also in chemical resistance, water resistance, and electrical insulation, that has a good kneadability (miscibility) into resins, and that enables to produce a material or an article, such as a resin composition, which is excellent in shapability. The present invention is an alumina-based thermally conductive oxide obtained by firing a starting material mixture containing an aluminum starting material. The aluminum starting material is at least one selected from the group consisting of boehmite, aluminum hydroxide, and alumina, the starting material mixture further contains at least one additional starting material selected from the group consisting of talc, a frit, a boric acid compound, a molybdenum compound, titanium oxide, a magnesium compound, a zinc compound, a zirconium compound, a phosphoric acid compound, and a tungsten compound, and the content of the additional starting material in the starting material mixture is 0.1 to 20 parts by mass based on 100 parts by mass of the aluminum starting material.
